| 摘 要： | 目的]研究不同磷肥施用量对烤烟产量及品质的影响。方法]通过田间试验研究不同的磷肥施用量对烤烟生长及烟叶产量和品质的影响。结果]不同磷肥施用量，对烤烟的生育期和前期长势影响不大，但后期长势较好；随着磷肥施用量的增加，烤烟株高逐渐增加，有效叶片数也逐渐增多，中、上部烟叶随着磷肥施用量增加，其叶长相应增加；随着磷肥施用量的增加，产量呈逐渐增加趋势，当磷肥施用量为157．5kg／hm^2时，产值最高，达39235．80元/hm^2，上等烟所占比例也最高，达45．61％，当磷肥施用量为315．0kg／hm^2时，产量最高，但烤烟质量下降。结论]当磷肥施用量为157．5kg／hm^2时，效果最好，磷肥施用量过高，会使烤烟品质下降。
